Ankle Flashcards
Talocrural Joint (TCJ) Consists of
Talus, Fibula/Tibia
TCJ Anatomical Movement
Plantarflexion/Dorsiflexion
TCJ Accessory Movement
Talar body rolls in mortise
Anterior/Posterior Glide
Talar Tilt
Excessive Movement of Talus (not an anatomical term)
TCJ Accessory Movement in Plantar/Dorsi Flexion
Limited Accessory Movement in DF
More Movement in PF
Lateral Ligaments of TCJ
Anterior Talofibular (ATFL)
Calcaneofibular (CFL)
Posterior Talofibular (PTFL)
ATFL Attachments
A: Neck of Talus
P: Lateral Malleolus
ATFL Limits/Assisted By
L: Inversion in plantarflexion
Assisted by: Fib. Longus and Brevis
CFL Attachments
P: Lateral Malleolus
D: Lateral surface of Calcaneus
CFL Limits/Assisted By
L: Inversion
Assisted by: Fib. Longus/Brevis
PTFL Attachments
Lateral: Medial surface of lateral malleolus
Medial: Posterolateral Talus
PTFL Limits/Assisted by
L: Dorsiflexion
Assisted By: Talar Body shape
Medial Ligaments of Ankle
Anterior Tibiotalar
Posterior Tibiotalar
Tibionavicular
Tibiocalcaneal
(Deltoid Ligament/Complex)
Medial Ligaments Attachments
P: All at Medial Malleolus
D: (Anterior Tibiotalar) Neck of Talus
Posterior Tibiotalar: Body of Talus
Tibionavicular: Navicular Bone
Tibiocalcaneal: Calcaneus
Subtalar Joints (Shapes, Type of Joint)
Talocalcaneal (Plane Shape, Synovial)
Talocalcalealnavicular (Ball and Socket, Synovial)
Considered discrete joints but always function together
Subtalar Joints Movements
Inversion, Eversion
STJ Ligament (Inside Sinus Tarsi)
Interosseous Talocalcaneal Ligament
Interosseous Talocalcaneal Ligament Location
Sinus Tarsi
Sinus Tarsi What is It?
Osseous Tunnel that runs from lateral to medial side of foot between talus and calcaneus
Divides Subtalar joint into anterior and posterior
